GeoHelix®-P2
Embeddable Passive Antenna Product Specification
Product Description Built patented PowerHelix® filtering antenna technology, GeoHelix-P2 embedded antenna smallest quadrifilar helix antenna available, providing high performance difficult applications. GeoHelix-P2 antenna ideal applications where:
device handheld, body-worn, otherwise surrounded high-dielectric materials that would de-tune conventional antennas; antenna tightly integrated with other antennas, e.g., Bluetooth®/GPS receivers GPS/GSM mobile phones; there tight constraints size device amount space allocated ground planes; orientation device random; antenna will embedded device. GeoHelix-P2 antenna balanced, which isolates from device enables antenna reject common mode noise resident device ground plane. construction materials antenna constrain near-field very small volume, therefore materials near antenna have negligible de-tuning effects antenna maintains pattern efficiency presence dielectric loading. dielectrically-loaded antenna, GeoHelix-P2 acts filter, attenuating signals from common frequencies much 30dB without external filtering. GeoHelix-P2 embedded antenna builds industry-leading performance GeoHelix-SMP external antenna, reducing size 30%, making even simpler embed product. antenna deployed with plastic tuning sleeve ensure on-frequency performance.

Radiation Pattern (dBic)
embedded GeoHelix-P2 antenna provides similar performance external GeoHelix-SMP antenna, with typical peak gain -2.8dBic, excellent beamwidth strong circular polarization. strength PowerHelix antenna technology immunity de-tuning presence dielectric loading, like human tissues. GeoHelix antennas retains efficiency polarization near human body. Conventional antennas lose 5-10dB gain similar circumstances. Though will electrically couple with ground plane, GeoHelix-P2 antenna expected increase efficiency 100% when mounted over ground plane near-field signal reflections. Configuration orientation ground plane with respect antenna will vary results, efficiency will decrease.
Typical Impedance
GeoHelix-P2 antenna optimized impedance simplify matching process. Smith chart showing typical impedance plot antenna been normalized resonant frequency antenna shown marker, bandwidth antenna shown dimensions loop. circle shows VSWR<=2.3:1 impedance mask. with pattern chart, important note immunity antenna loading factors close proximity. seen that impedance antenna changes very little until phantom hand placed inside radius 10mm from antenna.

Return Loss
Immunity from bio-loading effects demonstrated effectively through plot. While some change match observed phantom hand moved closer radiating section antenna, minimal de-tuning occurs. GeoHelix-P2 antenna also demonstrates sharp filtering response bands near desired resonant frequency.
